ATTACHMENT FOR SEWING-MACHINES.

To all whom it may concern:

Be it known that I, MARY MOCABE, a citizen of the UnitedStatesfresid'ingat New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Attachments.

for Sewing-Machines; and I do hereby*declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to new and useful improvements in attachments forsewing machines and more particularly to that class of portable machinesoperated by hand and my object is to provide a support for the handsewing'machine.

A further object is to provide means for operating the machine by footpower and a further object is to provide means for folding the supportand power applying mechanism, whereby when stored away it .will occupy aminimum amount ofspace.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claim.

In the accompanying drawings forming part of this application, Figure 'lis a front elevation of my improved supporting de vice, and, Fig. 2 isan'edge elevation thereof.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates a framewhich is preferably made in sections 2 and 3, the meeting ends of saidsections having brace bars 4: and 5, which are secured together by meansof hinges 6, so that when desired, the section 3 may be folded downagainst one face ofthe section 2 and in order to retain the section 3 inits extended position, a pin 7' is introduced through sockets '8 and 9on the section3 and similar sockets 10 and'll on the section 2, thesockets 8 and 11 being attached to vertical brace bars 12 and 13 on thesections 3 and 2, respectively, while the sockets 9 and 10 are attachedto the brace bars 5 and 1, respectively. 1

Rotatably mounted at the upper end of the section 3 is a belt wheel 14,which is 1'0- tatably mounted on a stub shaft 15, saidwheel beingprovided with a socket 15 into which the end of the handle employed inconnection with the hand operated machine is to extend and "as saidsocket is eccentrically mounted, the rotation of the wheelwill edgeof'the section 3 adjacent the is provided with a guard 27, which isadapt- Specification of Letters Patent.

operate the machine, the same as when the machine is operated by hand.

A belt 16 passes and around a driving wheel'17, which-is rotatablymounted on the vertical bracebar 13 of the section 2, said wheel havinga around the belt wheel 14 crank shaft 18, to the-,gcrank portion ofwhich is attached a pitman 19, the lower end of said pitman beinghingedly secured to a foot treadle 20 and by means of which poweris'applied to the driving wheel 17.

The treadle 20 is mounted upon 21, one end of which is attached to thesec tion 2 by means of a hinge 22, while the tapposite end thereof is,mounted in a support 23 and it will be readily seen that when the deviceis not in use, the shaft 21 and 'treadle mounted thereon may be swungupwardly and placed in alinement with the'face of the section 2 afterthe withdrawal of the usual connecting pin between the treadle and thepitm an 19.

Hingedly secured adjacent the upper end of the section 3 is a platform24:, upon which the machine is adapted to rest, said platform being heldin its elevated. position by meansof'a brace arm 25, one end of which ishingedly secured to the lower face of the "platform, while the opposite.nd thereof is adapted to engage a lug 26 on the brace bar 12, said armand lug being so arranged as to holdthe platform in a horizontalposition when the arm is engaged with the lug. One wheel 17 ed to ,keepthe garments or articles being sewed from coinin'gin contact with thedriving wheel and belt, one section of the uard also-having'an ear 28thereon, which 'orms a support for one end .of'the crank shaft 18.

In operation the section 2 of the frame 1 is raised to a verticalposition and the shaft 21 then. lowered to a horizontal position oruhtil the support 23 at the outer end thereof engages the floor, theshaft 21 being held in this position by any suitable means, such as acurved arm 29, the freeend of which is to be swung into engagement withthe brace bar 13 when the shaft is' in its lowered position and thesection 3 is then swung upwardly and the pin 7 introduced through itsrespective sockets, thereby. holding the sec tion 3 in alinement withthe section 2. The platform 24; is then raised to a horizontal positionand the arm 25 placed in engage- .ment with the lug 26, when the machinemay be placed on the platform and attached to the socket In order toprevent the machine from being turned backward, ratchet .30 is'fixed tothe wheel 17 and with said ratchet coiiperates a latch 31, which latchis prererably located upon the brace bar 13 and in position cooperatewith the ratchet 30 and hold the wheel against reverse rotation, 7

It will thus be seen that 1 have provided a convenient support for themachine and means for applying foot power thereto and I one that willoccupy but a minimum amount of space when in use, and further that whenthe sewing operation is completed, the frame and operating parts may becompactl fold-- ed together and readily transporte from lace to place orstored awe the wei ht V ands ize tifthe frame being such as to permit oftransbortation in a suitcase or similar object if desired, and it willbe readily apparent that the frame may be quickly set up for use orfolded together for transportation. 7

What I-claim is: In a combined supporting and power appll yingmechanism, the combination with a ame formed in sect1ons,sa1d sectionsbeing hlngedly secured together and a securing dey vice adapted to holdsaid sections in vertical alinement; of a shaft hingedly mounted ad-'jacent the lower portion of said frame, means to normally hold saidshaft extended at right angles to the frame, a support for the'outer endof the shaft, a treadle mounted on the shaft, a driving Wheel rotatablymounted on the frame, a crank shaft for the wheel, a pitman connectingthe driving treadle with the crank shaft, a belt wheel at the upper endof the frame, a belt extending In testimony whereof I have signed myname to thisspecification-in the presence of two subscribing witnesses.I I
